Peroxisomal Decarboxylation Reactions During Photorespiration (A) Possible pathways leading to reduction and/or decarboxylation of hydroxypyruvate. Unbroken lines represent known and confirmed reactions whereas dashed lines represent suggested alternative pathways. 1: glycolate oxidase, 2: catalase, 3: glutamate:glyoxylate aminotransferase, 4: serine:glyoxylate aminotransferase, 5: peroxisomal hydroxypyruvate reductase, 6: peroxisomal malate dehydrogenase, 7: cytosolic hydroxypyruvate reductase. (B) Relative abundance of photorespiratory intermediates for mutants under ambient air and short exposure to low CO2. White bars = ambient air (380 ppm), black bars = low CO2 (100 ppm). Results are mean ± SD of three biological replicates (and at least four technical replicates for each). Each genotype was compared to WT by Student’s t-test (significance level: * < 0.05; ** < 0.01; and *** < 0.001).(C) Representative integration of the CO2 release after switching the light off.(D) CO2 compensation point, (E) post-illumination burst, and (F) maximum rate of CO2 release for WT and photorespiratory mutants. Results are mean ± SD of three biological replicates (two technical replicates for each). All genotypes were compared to WT by Student’s t-test (significance level: * < 0.05; ** < 0.01; and *** < 0.001). (+) hpr1 cat2-2 was significantly different from hpr1 (significance level: + < 0.01).
